FIELD: information technologies.
SUBSTANCE: capacitance sensor element (10) comprises a base (1) in the form of a film or a plate, which is formed from an insulating material and has flexible or spatial shape, an electrode (2) of detection, arranged at least on a part of one surface of the base (1) and formed from a translucent conducting layer, comprising a carbon linear nanostructure, such as a carbon nanotube, and an outlet wire (3), which is an outlet from the detection electrode (2). The capacitance device of contact detection comprises a sensor element (10) and a circuit (60) to detect variation of capacitance, which is electrically connected with the detection electrode (2) via the outlet wire (3) and which determines variation of capacitance caused by approaching of a human body to the contact surface (4) or contact of a human body to the contact surface (4). The detection electrode (2) may be coated with a protective film, and the surface of the protective film may be used as the contact surface.
EFFECT: expansion of usage area due to increased extent of freedom of a shape of a capacitance detection device, such as a sensor panel.
